- the structure of the road vehicle is further equipped with electrical cabinets 35, in which devices sensitive to temperature fluctuations are accommodated by means of an air conditioning device.
- the function of the road vehicle according to the invention is as follows:
- a rail head quality can be achieved, the accuracy of which is not only comparable to that of new rails, but higher.
- the milling tool 13 is exchanged for a grinding wheel 14 by means of the tool changing crane 32. This work can be carried out for both sides in about 10 minutes.
- a road vehicle according to the invention can also be equipped on each side of the vehicle with two tool spindles 12 lying one behind the other, the first being equipped with a milling tool 13 and the second with a grinding wheel 14 (cf. 7).
- the individual steps for milling and grinding that must be carried out by the operating personnel are identical.
- the drive of the tool spindle 12 is started, then the cutting tool 13 or 14 is positioned in the horizontal direction, preferably by means of a photoelectric positioning system.
- the tool spindle 12 is then lowered hydraulically with the tool 13 or 14.
- Fine adjustment of the cutting tool 13 or 14 in the vertical direction is carried out by means of a copier.
- the drive for the bogies 17 and 18 then starts.
- the required machining depth takes place on the basis of the measured values recorded, a constant adjustment being made during the machining of a rail 2 on the basis of measured values processed online or by means of the copying shoe 24.
- the machining process described above namely first milling and then grinding, is the usual one. However, it is also possible to carry out machining only by milling or only by grinding, it being possible, for example, to first imagine roughing and then fine milling. These variants are based on the requirements placed on the track, especially since the requirements for side tracks are different to those for main tracks due to different speeds of the rail vehicles, etc.
